BACKGROUND OF THE INVENTION This invention concerns a process for making aminecarbotrithioates by reaction between a thiosulfonate and an aminecarbodithioate salt, advantageously an alkali metal or ammonium salt. The reaction is carried out advantageously in the presence of one or more organic liquids in which either or both of the reactants is dissolved or suspended, and at a temperature ranging between about 20 and about 150C, if desired under an inert atmosphere, e.g., nitrogen. The invention also concerns certain novel aminecarbotrithioates. The aminecarhotrithioates have biological activity, particularly in controlling microorganisms and other pests.

SUMMARY OF THE INVENTION The process of this invention is represented by the following equations:

and

ammo s s cim s s (IJNRml wherein n represents an integer from 1, to 2, to 3, to 4, to 5, to 6, to 7, to 8, to 9, to 10, to 11, to 12, and wherein R and R individually represent loweralkyl or hydrogen and together represent the remaining portion of a heterocyclic ring containing the nitrogen atom;

S (CIInnS S JNRKR4 (CH2)L|S S CNRJR4 5 (III) wherein R and R individually represent loweralkyl or hydrogen and together represent the remaining portion of a heterocyclic ring containing the nitrogen atom; wherein n represents 0 or 1; wherein each Z may be the same or different and represents loweralkyl, hydrogen, chloro, bromo, iodo, loweralkoxyl, nitro or loweralkylthio; and wherein m is 1, to 2, to 3, to 4, not more than two 2,, groups of which are iodo or nitro;

wherein R and R individually represent loweralkyl or hydrogen and together represent the remaining portion of a heterocyclic ring containing the nitrogen atom; R represents loweralkyl, phenyl, loweralkylphenyl, halophenyl or loweralkoxyphenyl; n is l, to 2 and X is O or onacrm s s (flJNRaRi wherein R and R individually represent loweralkyl or hydrogen and together represent the remaining portion of a heterocyclic ring containing the nitrogen atom; and wherein 'n is 10, toll, to 12, to 13, to 14, to 15, to 16, to 17, to 18, to 19, to 20;

wherein R and R individually represent loweralkyl or hydrogen and together represent the remaining portion of a heterocyclic ring containing the nitrogen atom.

As used in the specification and claims, the terms loweralkyl and loweralkoxy designate alkyl and alkoxy groups having from 1 to 4 carbon atoms, such as, for example, methyl, ethyl, propyl and butyl; and methoxy, ethoxy, propoxy and butoxy, respectively.

DETAILED DESCRIPTION OF THE INVENTION The process of this invention can be represented by the following equation for the monoaminecarbotrithio ate Formula (1) compounds, the reaction involved being equally operable in the preparation of Formula (II)-(VI) compounds:

wherein M alkali metal or ammonium cation R loweralkyl, aryl or substituted aryl R alkenyl, substituted alkenyl, 2-(loweralkylthio)ethyl, 2-(arylthio)ethyl, 2-(loweralkoxy)ethyl, 2-(aryloxy)ethyl or propargyl and wherein R and R, represents the remaining portion of a heterocyclic ring containing the nitrogen atom.

In the reaction, a single organic liquid or a mixture of two immiscible organic liquids or a mixture of a water immiscible liquid and water may be used as the reaction medium. For instance, the thiolsulfonate reactant may be dissolved in a water-immiscible solvent such as methylene chloride, chloroform, ethyl ether, benzene, toluene, xylene or commercial chlorinated solvents, and the carbodithioate salt may be dissolved in water. The two solutions are then mixed and vigorously agitated for a period of time from 5 minutes to hours advantageously at a temperature ranging between 20 and 150C. Again, both reactants may be completely soluble in a single organic solvent, or only one reactant may be completely soluble in the single organic liquid or neither reactant may be completely soluble in the single organic liquid. For another example, a solution of the thiosulfonate in ethanol can be added to a suspension of the carbodithioate salt in ethanol, and the resulting mixture stirred at the required temperature to cause reaction. Solvents useful in single organic liquid systems include ethanol, methanol, isopropanol, acetone, methylethylketone, methylene chloride, chloroform, benzene, toluene, or xylene. When operating above the boiling point of the solvent system, a pressure vessel is advantageously used.

The amounts of the reactants to be employed in the reaction are not critical, some of the desired products being obtained when the reactants are employed in any proportions. In a preferred method, good yields are obtained when employing substantially stoiehiometric proportions of the reactants. Bis( aminecarbotrithioates) are advantageously prepared by reacting two equivalents of an aminecarbodithioate, for example, sodium 4-morpholinecarbodithioate, with one equivalent of a thiosulfonate, for example, 2,2'-bis( phenylsulfonyl)diethyl sulfide to give thiodiethylene bis(morpholinecarbotrithioate). Up to 100 percent excess of either reactant is not deleterious, however.

Representative thiosulfonates useful in the process of this invention include o-nitrophenyl benzenethiolsulfonate, dinitrophenyl benzenethiolsulfonate, 2,3,3- tribromoallyl p-toluenethiolsulfonate, 2,3,3- tribromoallyl benzenethiolsulfonate, p-phenylene bis( methanethiolsulfonate pentamethylene bis(methanethiolsulfonate), allyl p-toluenethiolsulfonate, a,a'bis(methylsulfonylthio)-o-xylene, propargyl p-toluenethiolsulfonate, methyl methanethiolsulfonatc, Z-methylbenzyl benzenethiosulfonate, ethyl p-toluenethiolsulfonate, n-dodecyl p-toluenethiolsulfonate, benzyl p-toluenethiolsulfonate, Z-(methylthio)ethyl p-iodobenzenethiolsulfonate, 2-( methylthio)ethyl methanethiolsulfonate. 2,2- bis( phenylsulfonylthio )diethyl sulfide, 2( ethylthio )ethyl methanethiolsulfonate, 2-( phenoxy )ethyl benzenethiolsulfonate, 2-phenylallyl methanethiolsulfonatc, 2,2-bis(phenylsulfonylthio)diethyl sulfide and methylthiomethyl methanethiolsulfonate.

Representative aminocarbodithioate salts useful in the process of this invention include sodium, potassium, lithium and ammonium dithiocarbamate. dimethylaminecarbodithioate. diethylaminecarbodithioate, 1-piperidinecarbodithioate, and 4-morpholinecarbodithioate.

The novel compounds of this invention are particularly useful as pesticides for the control of various fungal and bacterial organisms and other pests such as Bacillus .s'ublilis, Staphylococcus aureus, Escherichia coli, Candida albicans, Trichophyton mentagraphytes, Venluria inaequalis, Piricutaria oryzae, Aembacter aerogencx, Salmonella typhosa, Candida pelliculosa, Pullularia pullulans, Rhizopus nigricans, Aspergillus terreus, Eimeria necatrix, Eimeria tenella and Daphnia.

In the test method, a paper cylindrical cage is provided, fitted on the bottom with a number 52 Whatman filter paper and on the top with a retaining screen. Twenty-five nymphal cockroaches are inactivated with CO and immersed in an aqueous dispersion of 1,000 parts per million by weight of the compound of Example 2 contained in the cage. The water is drawn off by suction through the filter paper. The nymphs are then fed with sugar water and left in the cage for three days, when a mortality count is made. Under such conditions, substantially complete control is attained. The same compound is separately dispersed in a series of melted nutrient agar samples to product a bacteriological culture medium containing 500 p.p.m. thereof by weight of ultimate medium. Each of these media is then poured into a separate Pctri dish and allowed to solidify. The solidified agar surface in each Petri dish is separately inoculated with one of Staphylococcus aureus, Bacillus subtilis, Aspergillus terrcus, Candida pelliculosa, Pullularia pullulans or Salmonella typhosa, the inoculation being carried out by mopping the agar surfaces with a swab from a 24hour broth culture of the organism. After 72 hours incubation at 30C. the agar surface of each Petri dish is examined for micro organisms. In each ofthe series. the control is I percent. A control culture. to which none of the compound is added. shows vigorous growth.

The compound of Example 3 is similarly I00 percent effective against Staphylococcus aureus and Bacillus subtilis at a concentration of 500 p.p.m.

The compound of Example 5 is similarly effective against Staphylococcus aureus. Candida albicans and Trichlorophyton mentagrophytes. but at I00 p.p.m. concentration. This compound is also effective in controlling Daphnia and Carassius auratus when I00 p.p.m. of compound is dispersed in water containing these organisms. Piricutaria orylae is controlled I00 percent by application of an aqueous dispersion containing I00 p.p.m. of compound. Amaranthus species is I00 percent controlled by application to the soil of lb./acre of the compound applied in aqueous dispersion as a drcnch to soil containing viable seed of said species.

The compound of Example 7 is I00 percent effective against the American cockroach at a concentration of 1000 p.p.m. used in the form of an aqueous dispersion. An aqueous dispersion of I p.p.m.. when sprayed on cucumber plants and potato plants. respectively, gives I00 percent control against Erysiphe cichoracearum and percent control against Phytophthora infestans.

The compounds of Example 24 is similarly percent effective against the American cockroach and against Staphylococcus aureus at 500 p.p.m.. and I00 percent effective against Candida albicans. Triehophyton mentagrophytes. Bacillus subtilis. Aspergillus terreus. Candida pelluculosa. Pullularia pullulans and Mycobacterium phlei. all at a concentration of I00 p.p.m.
